Embodiment Construction

[0020] Below by embodiment and in conjunction with accompanying drawing, the present invention will be further described:

[0021] to combine figure 1 — Figure 5 The heat conduction electric power steering controller shown is mainly composed of PCB board 1, base 2, cover plate 3, sensor signal connector 4, motor power connector 5, body signal connector 6 and body power connector 7 composition.

[0022] Both the base 2 and the cover 3 are injection molded by aluminum alloy, and a side wall extending downward is provided along the peripheral edge of the cover 3 , together with the base 2 , they form a rectangular controller housing. The PCB board 1 is mounted on the base 2 and located in the controller housing. The sensor signal connector 4 and the motor power connector 5 are integrally injection molded and installed on the front side wall of the cover plate 3 . The body signal connector 6 and the body power connector 7 are integrally injection-molded and installed on the r...

Abstract

The invention discloses a heat conductive type electric power steering controller. The controller comprises a printed circuit board (PCB), a base and a cover plate. Tapered support columns and a heat-conducting seat in a right trapezoid shape are integrally formed on the base. The PCB is disposed on the tapered support columns and located through two locating columns penetrating through the PCB, and the PCB is fixed to the heat-conducting seat by the combination with screws. The base and the cover plate are arranged together in a press fit mode. Mounting protrusions are inserted into corresponding mounting notches, the tapered support columns are disposed in the cover plate, and the cover plate and the base are made to be fastened tighter and tighter. Four columns which extend upwards and are distributed in a rectangular shape are integrally formed on the base, threaded mounting blind holes with the number identical to the number of the columns and the positions corresponding to the positions of the columns are formed in the back of the base, and multiple strip-shaped heat-conducting grooves extending left and right are formed in the back of the base. By means of the structure of the heat conductive type electric power steering controller, the problems of slight shaking between the base and the cover plate as well as between the PCB and the base after mounting and too high local temperature of the PCB are effectively solved; besides, the dustproof effect is achieved.

Description

technical field [0001] The invention relates to an electric power steering controller used in automobiles, belonging to the technical field of mechanical structures. Background technique [0002] The electric power steering controller is an essential part of the electric power steering control system, which consists of a PCB board, a base, a cover plate and a connector. The cover plate and the base together form a controller housing, and the PCB board is mounted on the base and located in the controller housing. There are four connectors in total, namely motor power connector, sensor signal connector, vehicle body power connector and vehicle body signal connector, and the four connectors are all installed on the side wall of the cover plate. [0003] The base and the cover are fixed together by pressing. In the actual production and use process, the base and the cover are occasionally pressed and not tightened after being pressed. The installation between the PCB board and ...
